The composition, levels, and spatial distribution of dissolved lipophilic marine algal toxins (LMATs) including cyclic imines (CIs), yessotoxins (YTXs), okadaic acid (OA) and its derivatives, pectenotoxins (PTXs), azaspiracids (AZAs), and brevetoxins (BTXs) in the coastal waters of Southeast China (Xiamen) and the South China Sea (Hainan Island and Beibu Gulf) were investigated and compared for the first time. Dissolved AZA3 was firstly detected in the coastal seawater of China. OA and PTX2 were widely distributed in the three areas studied. Gymnodimine (GYM), 13-desmethyl spirolide C (SPX1), YTX, and homo-yessotoxins (h-YTX) were found mainly in the South China Sea. The average ∑LMAT concentrations in the coastal waters of Xiamen, Hainan Island, and Beibu Gulf were 10.02 ng/L, 4.21 ng/L, and 44.27 ng/L, respectively. More groups and much higher concentrations of LMATs occurred in the South China Sea than that in the other sea areas of China.
首次对中国东南部（厦门）沿海水域以及南海（海南岛和北部湾）中溶解态亲脂性海洋藻毒素（LMATs）的组成、含量水平及空间分布进行了调查和比较，其中包括环亚胺（CIs）、虾夷毒素（YTXs）、冈田酸（OA）及其衍生物、pectenotoxins（PTXs）、azaspiracids（AZAs）和短裸甲藻毒素（BTXs）。在中国沿海海水中首次检测到溶解态AZA3。OA和PTX2在所研究的三个区域广泛分布。裸甲藻毒素（GYM）、13-去甲基螺旋环内酯C（SPX1）、YTX和高虾夷毒素（h-YTX）主要在南海被发现。厦门沿海水域、海南岛和北部湾中LMATs的平均总浓度分别为10.02纳克/升、4.21纳克/升和44.27纳克/升。南海中出现的LMATs种类比中国其他海域更多，浓度也更高。
